How to Sharpen A Filleting Knife

Like any other knife, a fillet knife can be sharpened although it is a slightly different method to sharpen fillet knives because of their shapes. There are three main methods to sharpen a fillet knife: a tabletop sharpener, a whetstone, and a grinding wheel.

  1. Tabletop Sharpener

2. Whetstone

3. Grinding Wheel

Types of Fillet Knives

  1. Manual Fillet Knife

Manual fillet knives require your physical strength to move through the fish to separate the flesh from the skin.

2. Electric Fillet Knife

Electric fillet knives have electric motors to provide the power needed to fillet the fish.

What To Look For When Choosing A Fillet Knife

  1. Blade Material

The composition of the blade is one of the important factors to consider when choosing a fillet knife. The two common blade materials are carbon steel and stainless steel. Carbon steel blades are harder and require more maintenance as it is not highly corrosion and rust-resistant. However, carbon steel blades are long-lasting because it is durable.

Stainless steel blades are more corrosion and rust-resistant. As a result, they don’t require a lot of maintenance like carbon steel blades. However, stainless steel blades are not as sharp as carbon steel blades. Hence, when choosing a fillet knife based on the blade material, you want to take these into consideration and choose what is most important to you.

2. Blade Thickness

The thickness of the blade is another important factor to consider when choosing a fillet knife. The thickness will determine how flexible the fillet knife is when it comes to following the contours of the fish and separating the flesh from the skin. The thicker the blade, the more rigid it is, and the thinner it is, the more flexible it will be.

3. Blade Length

Most fillet knife blades come in the range of 6 to 11 inches. The length of the blade will determine the size of the fish that you can fillet. For medium to large fish, a blade length in the range of 7 to 11 inches will work.

4. Blade Shape

The shape of the fillet knife is also important when choosing one. There are fillet knives that are curved while others are not curved. A curved edge allows you to use the entire length of the cutting edge to quickly and easily fillet a fish.

5. Bevel

How much bevel a fillet knife has is also very important. The bevel helps determine how razor-sharp the edge of the knife will be to pierce the flesh and separate it from the skin. Most fillet knives have a bevel between 12 and 17 degrees.

6. Tang

Tang is another important factor that helps determine how durable is the fillet knife. There are full tang and partial tang. A full tang knife has the steel of the blade running through the entire handle. This design renders a balanced feel and provides more control. You will save more of the fish flesh when you fillet or skin the fish.

Partial tang knives have the steel of the blade run halfway. As a result, you can’t apply a lot of pressure on the knife or it could get broken. A half-tang fillet knife may not be the best option to fillet a large fish.

7. Handle Material

The material of the knife handle is another factor to consider when choosing a knife. Most fillet knives have wooden, plastic, or rubber handles. Wooden handles are harder to maintain and could feel slippery when you are filleting a fish. Additionally, the wood may soak up odor from the fish and emit a bad odor.

Plastic and rubber handles have a firmer grip than wooden handles and they don’t keep odors. Most plastic and rubber handles are designed to be ergonomic which makes it easier to use them for a long period of time. They are easier to clean and come in different colors.

8. Safety

Some fillet knives have a safety feature to keep your fingers from the blade while cutting. These finger guards are found on the top of the handle, right behind the heel of the blade.
